Internet Facts

The prototype for the Internet was created in the sixties by the US Defense Department. To ensure that communication could be kept open in the event of a nuclear attack, it created a computer network known as Arpanet — the Advanced Research Project Agency Network.

The first attempt to connect two computers and allow them to communicate with one another was made by researchers at the University of California in Los Angeles and the Stanford Research Institute on 20 October 1969.

The first people to coin the term ‘internet’ were two scientists, Vinton Cerf (known as ‘father of the Internet’) and his collaborator Bob Kahn, who in 1974 devised a means by which data could be transmitted across a global-network of computers.

An Oxford graduate, Tim Berners-Lee, set up the first ‘www server’ (a Server receives and sends messages) to store the archive of the European Particle Physics Laboratory in Switzerland.

The first e-mail ever sent was in 1972 between computers in two American universities. The most frequently used search word on the net is «sex», typed in 1,550,000 times every month.

The most mentioned male on the Internet is President Bill Clinton, whose name is linked to 1,542,790 sites.

The most mentioned female on the Internet is the actress Pamela Anderson, whose name is linked to 1,542,282 sites.

The Internet

The Internet is a huge network of computers spanning this planet and is now started to bring in the surrounding area like space. Some computers like servers share data, others just surf the web as clients downloading the data. Public Internet began in the late 70’s. In the 70*s web users used an interface called telnet, but now that program is mainly obsolete. Telnet is most widely deployed in accessing college email accounts.

The Internet is very helpful, because it’s a huge database of knowledge, from the pictures of family trips to an analysis of quantum mechanics. Everyone should have the Internet because of its near instantaneous communication and huge wealth of knowledge. But how to go on the Internet and do a search for information we need. There are two ways to do it.

The first is when you know an internet address of data you need and the second one is when you try to find information you need by using a search program. In the beginning we have got to enter any browser you like. It could be an Internet Explorer, Netscape Navigator or Opera, etc. If we have a broadband connection, we connect to the Internet at once. If not, we have to set up and connect to our dial-up service. Finally, if we want to find some information in the Internet, we are to type an address of this data in the browser we use or simply use the existing search-programs such as the google search program, rambler search program, yandex search program or yahoo search program.

They are very simple and popular networks of sites. In these programs we can just type the word or name of thing, we would like to find and then press enter. A search program solves this problem. We get our results in the same window. After we get our results, we simply choose whatever site best matches our query or keep searching.

Besides data, one can get from the Internet, we can also send and receive e-mail or electronic mail. This internet service is cheaper than ordinary mail and much quicker. It is becoming popular day by day. We can get some news from the Internet, because there are many informational servers in the web.

Satellites and Telecommunications

Our world is becoming an increasingly complex place in which, we are very dependent on other people and organizations. An event in some distant part of the globe can rapidly and significantly affect the quality of life in our home country.

This increasing dependence, on both a national and international scale, forced us to create systems that can respond immediately to dangers, enabling appropriate defensive or offensive actions to be taken. These systems are operating all around us in military, civil, commercial and industrial fields.

A worldwide system of satellites has been created and it is possible to transmit signals around the globe by bouncing them from one satellite to an earth station and then to another satellite and soon.

Originally designed to carry voice messages, they are able to carry hundreds of thousands of separate simultaneous calls. These systems are being adopted to provide for business communications, including the transmission of voice and facsimile messages, data and video data.

It is probable that future wide use of satellites in the area of telecommunications will provide a great variety of information services to transmit directly into our homes, possibly including personalized electronic mail. The electronic computer is at the heart of many such systems, but the role of telecommunications is not less important- There will be a further convergence between the technologies of computing and telecommunications. The change of this kind will lead us to the database culture, the cashless society, the office at home, the gigabit-per-second data network.

One cannot doubt that the economic and social impact of these concepts will be very significant. Already, advanced systems of communication are affecting both the layman and the technician.

The new global satellite-communication systems offer three kinds of service.

The first one is voice messages. Satellite telephones are able to make calls from anywhere on the? Earth to anywhere else. That makes them especially useful to use in remote, third-world villages (some of which already use stationary satellite telephones), for explorers. Today’s mobile phones depend on earth-bound transmitters, whose technical standards vary from country to country. Satellite telephones can solve this problem, but it is not a cheap service.

The second service is messaging. Satellite messages have the same global coverage as satellite telephones, but carry text alone, which is extremely useful for those with laptop computers. As we see, the Internet works in space too. The only problem for ordinary users is one-way transmissions. This problem is solved by using combine transmissions, when you make a call using land communications and receive ordered information through your satellite plate.

The third service is tracking. Voice and messaging systems also tell their users where they are to within a few hundred meters. Combined with the messaging service, the location service could help rescue teams, to find lost adventurers, the police to find stolen cars, exporters to follow the progress of cargoes and so on. Satellite systems provide better positioning information to anyone who has a receiver for their signals.

To my thinking, satellite method of communication is the future for all kind of telecommunications.

Cyberterrorism

Defined broadly, the term «computer crime» could reasonably include a wide variety of criminal offenses, activities, or issues. The potential scope is even larger when using the frequent companion or substitute term «computer-related crime.» Given the pervasiveness of computers in everyday life, even in the lives of those who have never operated a computer, there is almost always some nontrivial nexus between crime and computers.

By the FBI’s definition, cyberterrorism is well beyond the scope of this paper. With increasing frequency this term is being used by the mass media. Absent any evidence of activity, we’ll leave it in the «eye of the beholder» to determine whether cyberterrorism is currently being deterred, is a phantom menace…or somewhere in between.

A key distinction between electronic civil disobedience and politicized hacking is anonymity. The motive for remaining secret is simple: the majority of politically motivated hacks are clearly illegal. Most institutions recognize that breaking into an opponent’s computer and adding, changing or deleting (HTML) code, even if it is juvenile graffiti, violates some other’s rights. Attitudes and opinions begin to diverge markedly around this point however. One person’s activist is another’s terrorist.

«A lot of groups are claiming that they’re hacking into sites for a higher moral purpose, but they’re hiding beyond anonymity or pseudonymity. Taking responsibility is not something we see happening.»

At the heart of this discussion is the question of motive. Opinions differ just as much within the hacker community as outside over the efficacy of certain actions. The spate of (zombie) DDoS attacks against prominent e-commerce sites that occurred in February 2000 sparked a debate between two prominent hacker collectives. The Electrohippies Collective claims the Internet as a public space liable to be used by groups and individuals as a means of protest. As activists, they admit no practical difference between how cyberspace and the street are used by society.

Recent actions on the Internet against e-commerce sites represent a fundamental disagreement about the purposes of the Internet, and the increasing emphasis on the use of the ‘Net as a vehicle for profitable trade rather than of knowledge and discussion.

The cDc says, the targeted sites were selected for their name recognition and prestige value, not for their commercial attributes or activities.

You may make yourself feel good and get a lot of attention, but when you crack a Web site, you are violating another person’s rights. …what does that mean? CRIME!

Great Inventions

Television (1920s)

The invention that swept the world and changed leisure habits for countless millions was pioneered by Scottish-born electrical engineer John Logie Baird. It had been realised for some time that light could be converted into electrical impulses, making it possible to transmit such impulses over a distance and then reconvert them into light.

Motor Car (late 19th Century)

With television, the car is probably the most widely used and most useful of all leisure-inspired inventions. German engineer Karl Benz produced the first petroldriven car in 1885 and the British motor industry started in 1896. Henry Ford was the first to use assembly line production for his Model Т car in 1908. Like them or hate them, cars have given people great freedom of travel.

Electricity

The name came from the Greek word for amber and was coined by Elizabeth I’s physician William Gilbert who was among those who noticed that amber had the power to attract light objects after being rubbed. In the 19th century such great names as Michael Faraday, Humphry Davy, Alessandro Volta and Andre Marie Ampere all did vital work on electricity.

Photography (early 19th Century)

Leonardo da Vinci had described the camera obscura photographic principle as early as 1515. But it was not until 1835 that Frenchman Louis Daguerre produced camera photography. The system was gradually refined over the years, to the joy of happy snappers and the despair of those who had to wade through friends’ endless holiday pictures.

Telephone (1876)

Edinburgh-born scientist Alexander Graham Bell patented his invention of the telephone in 1876. The following year, the great American inventor Thomas Edison produced the first working telephone. With telephones soon becoming rapidly available, the days of letter-writing became numbered.

Computer (20th Century)

The computer has been another life-transforming invention. British mathematician Charles Babbage designed a form of computer in the mid-1830s, but it was not until more than a century later that theory was put into practice. Now, a whole generation has grown up with calculators, windows, icons, computer games and word processors, and the Internet and e-mail have transformed communication and information.

Aeroplane

The plane was the invention that helped shrink the world and brought distant lands within easy reach of ordinary people. The invention of the petrol engine made flight feasible and the American Wright brothers made the first flight in 1903.

The achievement of science and technical revolution and our day-to-day life

As the years go forward our life becomes faster, a lot of new things appear, our mind develops and it cannot stop. It`s like a strong river which never ends to run and it is rapidly spreading all over the earth. Many centuries ago people even couldn`t imagine that we will be able to exchange information using telephone, fax, Internet as long as they couldn`t think that there are a lot of planets except our earth and that people can fly their. If we think how had everything developed, how many new things had appeared and how had the minds of people become so wide we even won`t be able to understand it because nowadays we cannot imagine our life without such inventions like lamps, ovens, central heating and others. During the centuries people have been invented the things to make our life easier. A great invention such as transport plays one of the most important roles in our life. We live in flats, can appear in different point of earth within a day, can say hello to people who live in another point of the world. All those things are a product of technical progress and it doesn`t stop to grow and develop. Nowadays we live surrounded by machines and other inventions. And with new inventions we become happier because nearly everything is making by machine not by ourselves. And from day to day appear more and more new things. And we don`t think about how the first inventions were created. The only thing we know that we never will return to the life which people lived a lot of centuries ago because there is no way back. Everything is handy. We use at home vacuum cleaners to clean the flat, ovens to cook, lifts to walk down in our houses, lamps to make our flats light…. There are a lot of such things like this, and we even don`t think about when and where and who invented it. And it`s so simple to us. And it`s so dear to us that we cannot even live without it. Our century is a century of developing informational connection. Faxes, TV, Internet, and Telephone became the most popular way of getting and sending information. One of the greatest inventions of the century, in my opinion is computer. It`s the coup in the technology. When Charles Babbage (1792-1871), a professor of mathematics at Cambridge University invented the first calculating machine in 1812 he could hardly have imagined the situation we find ourselves today. Computer becomes like a brain of human but the only thing it cannot do is to feel. The other things are easy to it. As everything computers also develop. The possibilities of it are so wide. It can do more than 500000 sums in a fraction of a second. Programming became one of the most useful and popular profession. Nowadays computers can pay wages, reserve seats on planes, control sputniks, compose music. Also everybody knows the words Cd Rom, a means of storing information on a disk to be read by a computer, e-mail, which becomes one of the ways to exchange information, the Internet — a network that is a way to get information, to communicate with people, to find everything you need. More and more people become Internet users because we can do so many things their and also cannot say all of them. You can chat there, find job, pay bills, get music, buy something, find referats, and know the latest news exchange information with other people in each point of earth by e-mail and a lot of other functions. As for me it became a usual thing to be connected to Internet. It attracts me by a wide variety of different kinds of information which is necessary to people. Of coarse I use a lot of other things of technology at home. And I think that the main point of such inventions as vacuum cleaners, which we use at home, radio, TV set, mixers, refrigerators, one of the most important thing in every flat all these were invented only after the invention of electricity. So I find the question about technical progress very wide and it`s impossible to say about all inventions. And in conclusion I want to say that the technical progress won`t stop and the machines will substitute everything except one the human.
